my program run with DM6441 processor.
config 1 : DSP 513MHz, ARM 256MHz, DDR2 162MHz.
my program need about 10mege cycles to process a frame of video.(measure by TSCL), and about 20ms.(measure on ARM side, using gettimeofday to calc the time.)
config 2: DSP 675MHz, ARM 337.5MHz, DDR2 162MHz
my program need about 20mege cycles to process a frame of video.(measure by TSCL), and about 30ms.(measure on ARM side, using gettimeofday to calc the time.)
Why the program need more cycles at higher DSP Frequency ?
